About the histogram
The histogram provides the user with a graphical version of the image data to help
determine the optimal image capture conditions. When an image is detected, the
histogram is displayed at the bottom of the screen.

axis displays the type of the gray levels. You can reduce the time that is taken to
view the band by stretching the signal. This can be achieved by dragging the cursor
at the left and right margins of the histogram, and moving them towards the center.
